Abstract: Methods and apparatus for out of service processing with varied behaviors. In an aspect, a method is provided for service acquisition. The method includes determining one or more conditions, wherein each condition is associated with at least one weight, detecting whether an out-of-service event has occurred, and if an out-of-service event is detected: identifying selected conditions and associated weights, and processing the associated weights to determine service acquisition "on" and "off" times. In an aspect, an apparatus includes condition logic configured to determine one or more conditions, wherein each condition is associated with at least one weight, and processing logic configured to detect whether an out-of-service event has occurred, and if an out-of-service event is detected, to identify selected conditions and associated weights, and process the associated weights to determine service acquisition "on" and "off" times.

Abstract: Techniques for efficiently performing system search to obtain service from a wireless system as quickly as possible are described. A terminal initially looks for service from a first (e.g., W-CDMA) system. The terminal identifies network(s) in the first system from which service was received in the past and performs acquisition on each network to look for service. If service is not found for the first system, then the terminal performs a search for a second (e.g., GSM) system. If service is found on the second system, then the terminal obtains service from the second system and avoids a frequency scan for the first system. Otherwise, the terminal performs a frequency scan for the first system using the search results for the second system. The terminal may obtain a list of RF channels detected for the second system and may omit these RF channels and possibly some other RF channels around these RF channels from the frequency scan.

Abstract: An apparatus, such as a subscriber unit or a base station within a spread spectrum communication system, may add one or more additional "virtual" paths to a list of candidate paths when assigning demodulation elements. These "virtual" paths are added as candidate paths even though a corresponding peak was not necessarily detected within a received spread spectrum system. The list of paths may include a first path having a time offset approximately equal to a time offset for one of the demodulation elements, and the virtual path having a short time separation from the first path. The time separation between the paths may be, for example, less than 2 chips.

Abstract: A method and apparatus for improving searching in a remote unit of a slotted mode, wireless, communication system. In a slotted mode communication system, the remote unit enters an "active state" during its assigned slot. While in the active state, a controller in the remote unit passes selected sets of search parameters to a search engine. The order that the searches are performed is based on the measured signal strength and the age of the measurement. The search engine performs searches using the selected sets of search parameters. Searching continues as long as the remote unit is in the active state. When the remote unit enters the inactive state, searching ceases. While in the inactive stage, the controller evaluates the results of the searches performed during the previous active state. During the next active state, the next sequence of searching is performed based on measured signal strength and the measurement age corresponding to the measurements made during the previous active state.
